Itsuki finds out that in addition to Stardust Labyrinths where the "Impurity Lords" dwell, there is also the 13th labyrinth, as well as the existence of the 13th maiden. He sets out to find the maiden. However, there is the possibility that the 13th is a male. Although not quite convinced, he seeks all the male candidates he could think of...
If I kept going, I would've 
been the one to give birth!
!إن استمرّ ذلك، كان أنا من سينجب
Dann hätte ich das Sternenkind geworfen!
¡Si seguía, yo habría dado a luz!
¡Poco más y me preña él a mí!
À ce rythme-là, c’est clairement moi
qui allais porter l’enfant !
Se l'avessi lasciato fare,
sarei stato io a partorire!
Daquele jeito, quem teria
que dar à luz seria eu!
Если бы так дальше пошло, 
это мне рожать бы пришлось!
